我收到错误信息：“变量的类型不完整，类型为” void”，但我找不到问题所在

Question

我必须计算向量的单词，然后将其放入包含单词的地图中。 然后，函数showFrequencies必须显示/打印地图。

map<string, int>CountWords(vector<string> words) {

    map<string, int> count;

    for(auto i = words.begin(); i != words.end(); i++) {

        count[*i]++;
    }

    return count;
}

void showFrequencies(CountWords(vector<string> name)) {

    for (map<string, int>::const_iterator it = count.begin(); it != 

count.end(); ++it) {


    cout << it->first << "\t" << it->second;}

}

int main(){

    vector<string> words = {"hello", "you", "hello", "me", "chipolata", "you"};

    showFrequencies(CountWords(words));

    return 0;
}

Answer 1

void showFrequencies(CountWords(vector<string> name)) {

应该

void showFrequencies(const map<string, int>& name) {
